Ichigo's mother, Masaki Kurosaki, is not related to Yhwach in any way.
Masaki was a Quincy, a race of humans with the ability to manipulate spiritual energy. Yhwach, the father of all Quincies, was a powerful being who ruled over the Quincy race. While Masaki was a Quincy, she was not a descendant of Yhwach or related to him in any way.
Masaki's Quincy powers were passed down to Ichigo, who inherited both Quincy and Shinigami powers. However, this inheritance does not make him related to Yhwach or any other Quincy.
It's important to remember that while Yhwach was the progenitor of the Quincies, he was not necessarily the father of every Quincy. His influence over the race was more about power and authority, not biological lineage.
In summary, Masaki Kurosaki, Ichigo's mother, was a Quincy but not related to Yhwach in any way.
